Err..OpenGL not Openglide:-/ Tried to use Max2D and the second Nehe Tutorial but doesnt work. Thought its possible to use Max2D and OpenGL like the Nehe Tut in one code/.exe? What did i wrong?

Or isnt it possible to simply mix Max2D with OpenGL?

I beleive all graphics are done with openGL so mixing 2d and 3d should be no problem.

I've not tried it, but at a guess you should be able to mix OpenGl with the inbuilt Max2D commands, seeming as BMAX is built around OGL. Anybody tried this and know the score with it?

Yes you can. The default OpenGL viewport is (-1,-1) to (1,1) though - when you use Graphics instead of bglCreateContext it sets it to (0,0) to (screen_width,screen_height). So if you're drawing a triangle that would fill the screen with the standard OpenGL viewport, it might just be displayed as one pixel in the top-left corner of the screen - or not at all.

Thank you very much, it works as you say. Dont know why i havent simply tested Graphics command in nehe tut.
